Description
Technical Field
The invention belongs to the field of lithium battery diaphragm production and manufacturing, and particularly relates to a system for quickly adjusting the concentration of a water washing solution in solidification and water washing equipment of a lithium battery oil system coating diaphragm.
Background
The high-performance lithium battery oil-based coating diaphragm is mainly used for power batteries, 3C product batteries and energy storage batteries. Compared with the existing water-based coating diaphragm, the oil-based coating diaphragm has the technical core that after the surface of the diaphragm is coated, the oil-based coating diaphragm enters a coagulation tank to coagulate the surface of the diaphragm, then enters a water washing tank to wash out redundant coagulating liquid on the surface of the diaphragm, and then enters a drying oven to dry the water on the surface of the diaphragm, so that the oil-based coating diaphragm has the advantages of good air permeability, puncture strength, safety, porosity, high temperature resistance and the like. The performance of the diaphragm has direct influence on the capacity, the circulation capacity and the safety of the battery, and the diaphragm with excellent performance can improve the capacity, the charge and discharge capacity, the circulation capacity and the safety of the battery, so that the diaphragm with excellent performance plays an important role in improving the comprehensive performance of the battery. The advantages of oil-based coated separator over water-based coated separator are far greater in terms of product force.
At present, in the process of producing an oil-based coating diaphragm, the coagulation and the water washing are very critical steps, and the applicant previously applies for a rapid coagulation and water washing solution concentration adjusting device with the application number of 2021108481086; in the device: the No. 1 coagulation tank is filled with a solvent with concentration A, and the No. 2 coagulation tank is filled with a solvent with concentration B (A > B); pure water is respectively filled in the No. 1, no. 2 and No. 3 water washing tanks, and the overflow path is the overflow of pure water in the No. 3 water washing tank to the No. 2 water washing tank; pure water in the No. 2 water washing tank overflows to the No. 1 water washing tank; the pure water in the No. 1 water washing tank overflows to the No. 1 coagulating tank; the coated diaphragm enters a 1# coagulation tank, a 2# coagulation tank and a water washing tank in sequence. The concentration of the liquid in the coagulation tank needs to be maintained in a certain range, if the concentration exceeds the range, the performance of the coated diaphragm can be greatly influenced, and after the coated diaphragm enters the 1# coagulation tank, the concentration of the solvent in the 1# coagulation tank can be increased due to the fact that the coated diaphragm is provided with the solvent; the concentration of the solvent in the No. 1 solidification tank is greater than that in the No. 2 solidification tank, and the diaphragm can bring the solvent in the No. 1 solidification tank into the No. 2 solidification tank, so that the concentration of the solvent in the No. 2 solidification tank can be increased; when the concentration of the solvent in the two coagulation tanks is increased, a certain volume of solution is discharged, and a certain volume of pure water is replenished, so that the aim of regulation is fulfilled. However, although the concentration of the solvent in the 1# and 2# coagulation tanks can be reduced to a certain extent by the step-by-step overflow, the process of reducing the concentration requires a certain time and a certain amount of solvent is wasted. And by practice we also find that this way has not met the current rapid production requirements, therefore, there is an urgent need for a system that can more rapidly achieve the concentration adjustment of the coagulation tank solution, which is also of great practical production significance.
